Creates context components from environment.
Creates context components from environment.
- configuration
play config.
- env
play environment.
- returns
an instance of JavaContextComponents with default messagesApi and langs.
-
def
createContextComponents(): JavaContextComponents
Creates java context components from environment, using Configuration.reference and Environment.simple as defaults.
Creates java context components from environment, using Configuration.reference and Environment.simple as defaults.
- returns
an instance of JavaContextComponents.

def
createJavaContext(req: Request[RequestBody], components: JavaContextComponents): Context
Creates a java context from a scala Request[RequestBody]
Creates a java context from a scala Request[RequestBody]
- req
the scala request
- components
the context components (use JavaHelpers.createContextComponents)
-
def
createJavaContext(req: RequestHeader, components: JavaContextComponents): Context
Creates a java context from a scala RequestHeader
Creates a java context from a scala RequestHeader
- req
the scala request
- components
the context components (use JavaHelpers.createContextComponents)
-
def
createResult(javaContext: Context, javaResult: Result): Result
Creates a scala result from java context and result objects
Creates a scala result from java context and result objects
- javaContext
the Java Http.Context
- javaResult
the Java Result
-
def
invokeWithContext(request: RequestHeader, components: JavaContextComponents, f: (Request) ⇒ CompletionStage[Result]): Future[Result]
Invoke the given function with the right context set, converting the scala request to a Java request, and converting the resulting Java result to a Scala result, before returning it.
Invoke the given function with the right context set, converting the scala request to a Java request, and converting the resulting Java result to a Scala result, before returning it.
This is intended for use by callback methods in Java adapters.
- request
The request
- components
the context components
- f
The function to invoke
- returns
The result

def
invokeWithContextOpt(request: RequestHeader, components: JavaContextComponents, f: (Request) ⇒ CompletionStage[Result]): Option[Future[Result]]
Invoke the given function with the right context set, converting the scala request to a Java request, and converting the resulting Java result to a Scala result, before returning it.
Invoke the given function with the right context set, converting the scala request to a Java request, and converting the resulting Java result to a Scala result, before returning it.
This is intended for use by methods in the JavaGlobalSettingsAdapter, which need to be handled like Java actions, but are not Java actions. In this case, f may return null, so we wrap its result in an Option. E.g. see the default behavior of GlobalSettings.onError.
- request
The request
- components
the context components
- f
The function to invoke
- returns
The result
